LIQUID-SOAP DISPENSER.

Specification of Letters Patent. Application filed March 14, 1913.

Patented Nov. 10, 1914. Serial No. 754,254.

vide a simple and efficient device for dispensing liquid soap, and to such ends, generally stated, the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

In the accompanying drawings which illustrate the invention, like characters 1ndicate like parts throughout the several views.

Refering to the drawings, Figure 11s a view in vertical section with some parts left in full, showing a jar and valve mechanism for dispensing liquid soap; Flg. 21s a horizontal section taken on the line a m on Fig.

1; and Fig. 3 is a plan view showing a lid clamping band removed from the jar.

The soap jar 1, which is preferably of glass, is provided with a cover 2 which is securely but detachably held to the jar bya channel-shaped clamping ring 3, the ends of which are drawn together by a short nutted bolt 4. The head on the upper edge of the jar and the projecting flange of the cover, are preferably rounded so as to fit the channel of the clamping ring 3, and the said cover is provided with a small air passage 5 which permits air to slowly enter the jar, it being understood that there Wlll be sufiicient leakage between the cover and the clamping ring to afford the necessary supply of air required to permit the free flow of soap from the jar. At its lower end, the jar 1 is provided with a tubular metallic coupling sleeve 6, the lower end of which is preferably threaded and screwed into the sleeve-like end 7 of a supporting bracket 8. This supporting bracket 8 is shown as provided with a base flange 9 adapted to be secured by screws, or otherwise, to a wall or other upright support. I

The supportin bracket 8 1s provided with an oblique tubu ar valve chamber 10, the

lower portion of which intersects the chamber of the neck 7. Working in the valve chamber 10 is a plunger valve 11, the lower end 12 of which is in the form of a truncated cone, the outer end of which normally projectsthrough a conical discharge passage formed in the extreme lower end of the said valve chamber. lThe stem of thevalve 12 works through a suitable stufiing box 13 applied to the upper end of ber. 10. A spring 14 is compressed between the stuiling box 13 and a collar 15 on the valve 11. This collar 15 never leaves the cylindrical upper portion of the valve chamber 10 and closely fits the walls thereof, so that it affords a guide insuring true axial movements of the valve. This valve 11, for the purpose of distinction, is herein designated as the primary valve. For direct coiiperation with the lower end of the coupling sleeve 6, I also provide a valve 16 herein designated-as the secondary valve. This valve 16, when raised, closes the passage through the sleeve 6, and it is arranged to'be moved into a closed position when the pr mary valve 11 is moved intonn open position, and conversely, to be moved into an open position when the said primary valve 1s moved into a closed position. This movement, as shown, is accomplished by a link 17, the upper end of which is pivotally connected to the said valve 16 and the lower end of which is pronged and works in a channel 18 formed in the said valve 11.

An operating lever 19, which, as shown, isbifurcated so that it straddles the arms of the bracket 8, is pivotally connected to the latter at 20, and its upper end straddles the upper end of the stem of the valve 11 and engages a stop in the form of a washer 21 secured to the on of the said valve stem by a pin or otherwis Normally, the spring 14 holds the primary valve closed and the secondary valve opened and the lever 19 in the position shown in Fig. 1. ously open the primary valve and close the secondary valve, the lower end of the lever 19 is moved outward or toward the left in respect to Fig; 1, and its movement in this dlrection will be limited by the engagement of the edge of its flange 19 with the inner edge of the arms of the bracket 8.

With this arrangement, it is evident, when the valves are in normal position shown in Fig. 1, the liquid soap will run from the jar through the sleeve 6 and will fill the chamber within the sleeve or hollow head 7 of the the valve chain To simultane bracket 8. Then when the primary valve is moved into an open position and the secondary valve closed, the predetermined amount of liquid soap contained in the head 7 will be discharged for use. This prevents a waste of the liquid soap. Obviously, where there is but 'a single valve, the soap will run from the jar as long as the said valve is held ope'n and this will occasion a great loss and wasteiof the soap, especially when the dispensing device is used in public places where the persons using the soap do not pay forthe same, and consequently, do not have an incentive for economy.

The dispensing device described, while of small cost and of simple construction, is efficient for the purposes had in view.

What I claim is:

1. The combination with a soap container, of a bracket supporting said container and having a hollow head formed with a soap delivery conduit and an obliquely intersecting valve chamber, a spring-pressed plunger valve working in said valve chamber and normally closing the discharge end of said conduit, means tormoving' said plunger, a secondary valve for closing the upper extremity of said soap conduit, 2. link-connecting said secondary valve to said primary valve and causing the former to be closed when the latter is opened, and vice versa.

2. The combination with a soap container, of a bracket supporting said container and having a hollow head formed with a soap delivery conduit and an obliquely intersecting valve chamber, a spring-pressed plunger of a bracket supportingsaid container and having a hollow head formed-with a soap delivery conduit and an obliquely intersecting valve chamber, a spring-pressed plunger valve working in said valve chamber and normally closing the discharge end of said conduit, a secondary valve, for closing the upper extremity of said soap conduit, a link connecting said secondary valve to said primary valve and causing the former to be closed when the latter is opened, and vice versa, and a lever pivoted to said supporting bracket and connected to the rojectmg stem of said primary valve, the said lever having a portion engageable with the said bracket to limit its movement in a direction to open said primary valve.

In testimony whereof I aiiix my signature in presence of twowitnesses. MARINUS J. G. NYBORG.
